More than 200 veterans and military families from North Carolina and Pennsylvania are calling Republican efforts to challenge overseas ballots “a betrayal,” in an open letter backed by the Harris campaign and signed by Congress. Democrats.

Republican processes in both states have questioned the legitimacy of overseas ballots, a move the Harris campaign coalition said was designed to “undermine the ability of our military families and veterans living overseas to vote.”

“For those of us who sacrifice so much for this country, to have the right to vote questioned or prevented is nothing short of a betrayal,” the group said in the letter, which was obtained by Newsweek.

Pennsylvania Democratic Reps. Chrissy Houlahan and Chris Deluzio; former Representative Christopher Carney, Democrat of Pennsylvania; and Meg Snead, a former top Pennsylvania state official, signed the letter.

The group also criticized the former president Donald Trump for using lawsuits brought by the Republican National Committee and other groups to amplify false claims of voter fraud.

Trump said, without evidence, last month that Democrats were violating a decades-old law by sending out ballots for members of the military and others living abroad without verifying their US citizenship.

“Democrats talk about how they are working so hard to get millions of votes from Americans living abroad,” Trump said in a late September post on Truth Social, adding, “In fact, they are preparing to cheat!”

Newsweek has reached out to the RNC and the Trump campaign for comment.

Last week, a Michigan state judge dismissed an RNC lawsuit challenging votes cast abroad by people who have never lived in the United States. The judge called the challenge an “11th-hour attempt to disenfranchise” voters.

A state judge in North Carolina also dismissed a similar GOP lawsuit last week, writing that there is “absolutely no evidence” of voter fraud in the matter.

The RNC said in a statement that it will appeal the rulings. A separate RNC lawsuit on the matter in Pennsylvania is still pending.

The letter from the Harris campaign coalition comes as early voting is underway in key states that will likely determine the outcome of the race.

Less than two weeks before Election Day, Harris and Trump recently made several trips to North Carolina, Pennsylvania and other battleground states in hopes of boosting voter turnout.
